1 Freescale Generic ASoC Sound Card with ASRC support
3 The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
4 SoCs connecting with external CODECs.
6 The idea of this generic sound card is a bit like ASoC Simple Card. However,
7 for Freescale SoCs (especially those released in recent years), most of them
8 have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
9 this is a specific feature that might be painstakingly controlled and merged
12 So having this generic sound card allows all Freescale SoC users to benefit
13 from the simplification of a new card support and the capability of the wide
14 sample rates support through ASRC.
16 Note: The card is initially designed for those sound cards who use AC'97, I2S
17 and PCM DAI formats. However, it'll be also possible to support those non
18 AC'97/I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as
19 long as the driver has been properly upgraded.
22 The compatible list for this generic sound card currently:
25 "fsl,imx-audio-cs42888"
27 "fsl,imx-audio-cs427x"
28 (compatible with CS4271 and CS4272)
30 "fsl,imx-audio-wm8962"
31 (compatible with Documentation/devicetree/bindings/sound/imx-audio-wm8962.txt)
33 "fsl,imx-audio-sgtl5000"
34 (compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)
36 "fsl,imx-audio-wm8960"
40 - compatible : Contains one of entries in the compatible list.
42 - model : The user-visible name of this sound complex
44 - audio-cpu : The phandle of an CPU DAI controller
46 - audio-codec : The phandle of an audio codec
48 - audio-routing : A list of the connections between audio components.
49 Each entry is a pair of strings, the first being the
50 connection's sink, the second being the connection's
51 source. There're a few pre-designed board connectors:
57 * AMIC (stands for Analog Microphone Jack)
58 * DMIC (stands for Digital Microphone Jack)
60 Note: The "Mic Jack" and "AMIC" are redundant while
61 coexisting in order to support the old bindings
62 of wm8962 and sgtl5000.
66 - audio-asrc : The phandle of ASRC. It can be absent if there's no
67 need to add ASRC support via DPCM.
69 Optional unless SSI is selected as a CPU DAI:
71 - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
73 - mux-ext-port : The external port of the i.MX audio muxer
